scope:
Specifies an ultraviolet (UV) photometric method for the determination of ozone in ambient air. The method is applicable to the determination of ozone concentrations in the range 2 ug/m3 (volume fraction of 1x10-9) to 2 mg/m3 (volume fraction of 1x10-6 ). This standard uses the reference conditions of 25°C and 101,25 kPa; however, reference temperatures of 0°C and 20°C are also acceptable.
